Flame cutting machine

Abstract

A flame cutting machine includes a unit which photoelectrically scans a line curve or edge with at least one scanning beam receiver and with the output signals conducted to a leveling motor connected to a component analyzer for controlling two coordinate motors and with the scanning beam receiver and the leveling motor and the component analyzer mechanically in direct connection with one another.

What is claimed is: 
     
       1. In a cutting machine, especially a flame cutting machine, having a unit which photoelectrically scans a line curve or edge, and which has at least one scanning beam receiver, the output signals of which can be conducted to a leveling motor whereby the leveling motor is connected with a component analyzer for controlling two coordinate motors, the improvement being said scanning beam receiver and said leveling motor and said component analyzer being mechanically in direct connection with one another. 
     
     
       2. Cutting machine according to claim 1, characterized therein that said scanning beam receiver is attached onto a disc type printed circuit, said printed circuit being connected to one end of the shaft of said component analyzer, said component analyzer being designed as a sine-cosine potentiometer, and the other end of said shaft being connected with a direct current shunt-wound motor of low load capacity. 
     
     
       3. Cutting machine according to claim 2, characterized therein that contactable impulse markings are provided by means of sliders, and said sliders and said markings being connected with said leveling motor via an impulse stage which serves for selecting the direction of cut. 
     
     
       4. Cutting machine according to claim 1, characterized therein that contactable impulse markings are provided by means of sliders, and said sliders and said markings being connected with said leveling motor via an impulse stage which served for selecting the direction of cut.
